Wireless Site Survey Faq
A wireless site survey is the first step in deploying a wireless network. It involves studying a facility to understand radio frequency (RF) behavior, discover coverage areas, check for interference, and determine optimal access point placement. Key steps are obtaining facility diagrams, visually inspecting for barriers, identifying user areas, determining preliminary access point locations, performing surveys to verify locations, and documenting findings. Site survey tools help identify areas of weak signal or interference. It is important to use the same access point models for the survey that will be deployed.

Performance Comparison of Energy Detection Based Spectrum Sensing for Cogniti...
With the rapid deployment of new wireless devices and applications, the last decade has witnessed a growing
demand for wireless radio spectrum. However, the policy of fixed spectrum assignment produces a bottleneck for more
efficient spectrum utilization, such that a great portion of the licensed spectrum is severely under-utilized. So the concept of
cognitive radio was introduced to address this issue.The inefficient usage of the limited spectrum necessitates the
development of dynamic spectrum access techniques, where users who have no spectrum licenses, also known as secondary
users, are allowed to use the temporarily unused licensed spectrum. For this purpose we have to know the presence or
absence of primary users for spectrum usage. So spectrums sensing is one of the major requirements of cognitive radio.Many
spectrum sensing techniques have been developed to sense the presence or absence of a licensed user. This paper evaluates
the performance of the energy detection based spectrum sensing technique in noisy and fading environments.The
performance of the energy detection technique will be evaluated by use of Receiver Operating Characteristics (ROC) curves
over additive white Gaussian noise (AWGN) and fading channels.

Levelling
1. Levelling is used to determine relative heights and elevations of points and establish points at required elevations. It involves using instruments like levels and staffs.
2. There are different types of levels (dumpy, tilting, wye, automatic) and staffs (self-reading, target). Precise levelling is done to establish permanent benchmarks.
3. Adjustments must be made to level instruments during setup and permanently. Methods like differential, profile and cross levelling are used depending on the task. Reciprocal levelling involves backsight-foresight exchange to check for errors.
Basics Of Surveying
Surveying is used at various stages of a construction project from conceptual planning to maintenance. It involves measuring positions and elevations to determine spatial relationships and enable engineering design and construction. Common surveying methods include chain, compass, theodolite, plane table, tachometric, aerial photographic, and remote sensing surveys. Levelling specifically refers to determining relative elevations and is important for engineering works like establishing rail and road alignments and profiles. Key levelling instruments are dumpy level, tilting level, automatic level, and digital level.

SON (Self Organizing Networks) An analysis of its benefits in the mobile domain
Mobile Telecommunications Networks over the time has grown in
complexity and has reached the stage at which automations are now
indispensable for running a modern day mobile network. Crucial areas of network
such as design, planning, and optimization need a real time automation solution.
This is why the SON technology was developed. SON is a dynamic plug and play
system of hardware and software bundle which when connected to the
telecommunications network would automatically configure, optimize and heal the
network.
As with every new technology, there is always a degree of scepticism
that comes along and it is quite important to validate its functioning before we
accept it. The aim of this project is to analyse the three key features of SON i.e.
Load Balancing / ANR on 3G network, RET feature analysis on LTE network and
GSM spectrum Management on 2G network. It is intended to implement these
features on a live network and see the overall gain in the network performance. A
critical analysis is done to see the magnitude of impact due to SON. It is also
intended to find out areas where SON did not work well and had issues with its
implementation, working and accuracy.
In this project the main functionality of SON was closely reviewed when it was
implemented in an urban cluster. The KPI gains were measured in the area of
capacity, coverage, load balancing and quality improvements. The final result not
only gauged the magnitude of performance improvement but also highlighted the
complexity and drawbacks of the SON solution.
Some remarkable improvements in the network quality were observed
especially in the 3G and 2G network but there were couple of areas where SON
had issues and had failed to achieve what expected. These were noted as
learnings and areas of future improvement.

Fiber optic test issues ¨c what to measure and why
The document discusses the need to properly test fiber optic installations to support new applications like Gigabit Ethernet and 10 Gigabit Ethernet. Generic cable standards are not sufficient and a tester needs to automatically check against application-specific limits. There are currently seven different sets of length and loss limits for variants of Gigabit Ethernet, and 10 Gigabit Ethernet will likely require many more sets of complex testing limits. A field tester should keep track of the different application test limits and produce a test report with pass/fail results for each network application and generic cable standards.
Trends and evolution of optical networks and technologies

- Components research focuses on higher performance devices for functions like switching, modulation, and amplification,
Cell phones and cancer what is the evidence for a connection
This review article summarizes the existing evidence on the potential connection between radiofrequency (RF) radiation from cell phones and cancer. There have been numerous allegations that cell phones cause cancer based on media reports and legal cases. However, the epidemiological evidence for an association between RF radiation and cancer is found to be weak and inconsistent. Laboratory studies generally do not suggest that cell phone RF radiation has genotoxic or epigenetic activity. A cell phone RF radiation–cancer connection is also considered physically implausible. Overall, the evidence for a causal relationship between RF radiation from cell phones and cancer is deemed to be weak to nonexistent based on this review of the human, animal, and cellular evidence.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

- 3. 1 Overview Site survey is a hard work that need patient and carefulness。 The Engineer must survey seriously with responsibility. Any doubtful problem must be checked and survey to get the exact and true data. Only the exact and detailed survey report can ensure the network plan. The site survey is the base of network plan. 2 Site survey for network plan 2.1 How to make a choice of site and do the survey The following is the common rule of survey of new site: Network engineer must do site survey with the operator. The network plan engineers give the suggestion of location of new site. The operator takes the responsibility of negotiation with the owner of land and house. The other engineers take the responsibility of machine room building, transmission, power and towers. The network engineer through the survey, get the information of wireless propagation environment, the traffic around the site. Get the basic information of the new site. The location of new site can be chosen through the coverage, traffic, condition of build new site, and cost of new site. The following is the principle to build new site. The new site should locate the ideal location of cellular mesh. The windage of location can’t be more than one quarter of the coverage radius of the site. The density of the site distributing must be according with the distributing of traffic. At the beginning of the building network, the important area and hot spot must be covered well. At the city center, the height of small cell (the radius is about 1~3km) should be higher the average height of the buildings but lower than the highest building . Some micro cell, the antenna must lower than average height of the building. In the rural 第3页 共6页
- 4. area, the investigation whether some block between the site and the main coverage area. The big building or some big building that will be built soon can’t block the antenna. Avoid build the site with radio station and radar station and other strong interference source. If these kinds of location must be selected, the test of scanning the frequency to find the frequency interference before building. Avoid building new site in the forest, if the site in the forest, the antenna must be higher than the top of tree. The building, power, the place must be thought about. Select the cost low house as the new site location. If the location doesn’t affect the network quality, the exiting building and tower have the priority as the location of new site. 2.2 Personal and equipment for site survey Commonly the equipment is needed for site survey： 1．GPS Globe Position System, Measure the longitude, latitude, attitude 2．Compass The direction 3．Test Mobile Test the signal 4．Rule 5．Telescopes (Optional) 6．（Digital）Camera(Optional) 7．Drive Test Equipment (Optional) 8．Car Personal needed： 1． Driver 第4页 共6页
